        <p>
          <span class="application">Gavl</span> is short for Gmerlin Audio
          Video Library. It is a low level library that handles the details
          of audio and video formats like colorspaces, samplerates,
          multichannel configurations etc. It provides standardized
          definitions for those formats as well as container structures for
          carrying audio samples or video images inside an application.
        </p>
        <p>
          This package is known to build and work properly using an LFS-9.1
          platform.
